2016 Mercedes-Benz E 1.9L Diesel · C4 AOW

The 2016 Mercedes-Benz E presents a mixed roadworthiness picture where intermittent advisories punctuate a generally stable test record. The latest MOT conducted on 2026-06-27 returned a clean pass with no defects, confirming the vehicle remains roadworthy at this stage. However, the history reveals a pattern of recurring brake pad wear across three separate years—first noted in early 2021 with both front and rear pads flagged as thin (1.1.13 (a) (ii)), followed by a nearside rear tyre approaching legal limits in mid-2024 (5.2.3 (e)). These advisories suggest progressive wear on braking components and tyre longevity, even though each individual test result was positive. The absence of outright failures contrasts with the presence of these warnings, indicating the car has survived its lifetime without catastrophic breakdowns but requires attention to the highlighted systems before considering it fully reliable. At 79,501 miles on its 10-year lifecycle, the vehicle accumulates approximately 7,950 miles annually—a rate consistent with moderate daily or weekly use rather than extreme commuting demands. The mileage progression between tests shows a gradual increase, with the most substantial jump occurring around the 2024-2025 period when the rear tyre reached its warning threshold and the brake pad advisory reappeared. There are no large gaps in the MOT schedule, and the car has not sat idle for extended periods that would typically produce acceleration in mileage figures. The steady accumulation aligns with normal driving patterns for a model of this age, suggesting the odometer reading reflects genuine operational use rather than artificial inflation or under-maintenance scenarios. Focusing on the flagged components, the rear brake system warrants particular scrutiny given the two separate brake pad advisories spanning nearly four years. During a test drive, the driver should monitor for any pedal travel variations, pulsations through the chassis when applying pressure, or unusual noises emanating from the wheel wells when turning—signs that could indicate caliper binding, piston leakage, or worn pads requiring replacement. The nearside rear tyre reported in 2024 may still be in service depending on current tread depth, but if the issue persisted or worsened, inspecting the tyre sidewalls for cracking or uneven wear would reveal whether the original advisory resolved itself or indicates deeper structural fatigue in the tyre bead or surrounding suspension geometry. Additionally, while the 2023 brake pad advisory was resolved by the subsequent 2024 pass, any residual play in the brake caliper mounts or hose connections should be checked for signs of leakage or hard clamping that could affect braking performance. Finally, the 2021 and 2023 brake pad advisories provide a clear signal that the front and rear disc assemblies have experienced significant material loss over time, which is common for vehicles with regular use but does not necessarily preclude safe operation if the pads are replaced promptly. For a prospective buyer, the priority should be verifying that all brake components have been replaced according to the correct intervals and that the new pads are properly seated with adequate friction material. The rear tyre situation requires confirmation that the current tread is within legal limits and free of sidewall damage, especially given the earlier report of slight damage to the offside front outer tyre in late 2019. A thorough visual inspection of suspension linkages and subframe connections, particularly where metal-to-metal contact areas were previously flagged for corrosion, will help determine whether additional rust repair is needed before committing to purchase. Testing the vehicle on varied surfaces—such as rough pavement versus smooth tarmac—to assess handling consistency and braking stability offers practical insight into whether the recurring advisories represent isolated incidents or ongoing mechanical issues that could impact safety over the remaining lifespan of the car.
